WebSmall nuclear RNA ( snRNA) is a class of small RNA molecules that are found within the splicing speckles and Cajal bodies of the cell nucleus in eukaryotic cells. The length of an average snRNA is approximately 150 nucleotides. They are transcribed by either RNA polymerase II or RNA polymerase III. [1] WebA) The genes coding for them are on plasmids. B) They cause food-poisoning symptoms. C) Nisin is a bacteriocin used as a food preservative. D) They can be used to identify certain bacteria. E) Bacteriocins kill bacteria. Answer: B 7 In Figure 8.1, which colonies are streptomycin-resistant and leucine-requiring? A) 1, 2, 3, and 9 B) 3 and 9

WebStructure of the ribosome A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain). Web(1) RNase P is an endonuclease that cleaves the precursor to generate the 5' end of the mature tRNA. (2) RNase F is an endonuclease that cleaves the precursor 3 nucleotides past the 3' end of the mature tRNA. (3) RNase D is an exonuclease that trims in a 3' to 5' direction to generate the 3' end or the mature tRNA. Figure 3.3.3. phil nevin age
